Summary

Story summary

Insect metamorphosis began about 480 million years ago, when early insects hatched as smaller versions of adults.
About 400 million years ago, genetic mutations led to incomplete metamorphosis, with insects emerging as nymphs.
Eventually, complete metamorphosis evolved, with larvae bearing no resemblance to their parents.
Researchers understand some genetic controls, but the origins remain unclear, prompting ongoing entomology investigations.
